不同施肥处理对黄淮地区大白菜产量及养分利用率的影响
Effect of different fertilization treatments on the yield of Huang-Huai region cabbage and nutrient use efficiency
摘要
Abstract
In this experiment, we designed eight processing groups of treatment to study the absorption of NPK in cabbage and the fertilization residues in soil, through the application of different ratio of organic and inorganic fertilizer including urea, potassium sulfate, compound fertilizer, calcium superphosphate and dried chicken manure, etc. The results of 8 fertilization treatments of random replicates showed that the combined rate of organic and inorganic fertilizer achived optimum effect in the general when mass fraction was 3:1. The soil residues of NPK were enriched in the topsoil. The absorption of NPK in plants showed an increase-decrease trend. The effective utilization rate is 36. 31% for nitrogen fertilizer, 27.67% for phosphate fertilizer and 43.05% for potash fertilizer.关键词
